Introduction

AZ2210040012 is a precision OEM-grade transmission shim exclusively designed and manufactured for SINOTRUK heavy-duty truck transmission systems. As a critical precision adjustment component in the gearbox assembly, this shim is responsible for controlling gear clearance, bearing preload and axial assembly tolerance. Produced in strict accordance with original factory dimensional standards and heavy-duty automotive manufacturing specifications, it features ultra-flat precision, uniform thickness and stable mechanical properties. It effectively eliminates abnormal transmission noise, gear jitter and premature part wear caused by assembly clearance deviation, maintaining the optimal assembly state and long-term operational stability of the truck transmission under high-load and long-distance driving conditions.

Key Features

✅️Standard OEM Dimension & Perfect Vehicle Matching

Featured with standard part number AZ2210040012, this transmission shim fully matches the original assembly tolerance parameters of SINOTRUK heavy truck gearboxes. It achieves zero-error fitting for designated transmission assembly positions without cutting, bending or secondary trimming. It serves as a professional direct replacement for worn, deformed or missing original shims, ensuring 100% assembly conformity.

✅️High-Precision Tolerance Control & Accurate Gap Adjustment

Manufactured with micron-level thickness calibration and flatness processing, the shim delivers extremely precise clearance compensation. It accurately calibrates gear meshing gaps and bearing axial clearances, effectively solving common problems such as transmission gear collision, abnormal rattling noise and unsmooth gear shifting caused by excessive or insufficient assembly gaps, realizing standardized and precise transmission assembly.

✅️Premium High-Strength Steel Material & Wear Resistance

Adopting high-quality high-tensile carbon steel raw materials with integral stamping and fine polishing treatment, the shim features high hardness, strong compressive resistance and excellent fatigue resistance. It can withstand long-term mechanical extrusion, high-frequency vibration and variable load impact inside the gearbox, avoiding thinning, deformation, warping and abrasion, and maintaining stable precision for a long service life.

✅️Excellent Stability & Transmission System Protection

With uniform stress-bearing performance and stable physical properties, the shim maintains consistent clearance accuracy during long-term high-load operation. It optimizes the gear meshing state of the transmission, reduces friction loss between transmission components, lowers operating temperature and mechanical loss, and effectively delays the wear and aging of gears, bearings and synchronizers, greatly improving the overall service life of the gearbox.

✅️Strict Industrial Quality Certification & Harsh Environment Adaptability

All finished shims undergo strict dimensional inspection, flatness testing, hardness detection and anti-rust treatment. With stable mechanical performance and strong oxidation resistance, it adapts to various harsh working conditions including heavy-load freight, complex road conditions and long-hour continuous operation, featuring low failure rate and high operational reliability.

✅️Easy Assembly & High Maintenance Cost Performance

Standardized finished size allows quick and convenient installation without professional modification. It effectively solves various transmission abnormal faults caused by clearance mismatch, greatly reducing subsequent gearbox maintenance frequency and repair costs. It is an essential high-cost-performance precision accessory for SINOTRUK truck transmission overhaul and daily maintenance.
